Zusammenfassung:The invention describes a highly efficient catalytic pollution control process for removing N2O from gaseous mixtures. The process utilizes catalysts derived from anionic clay minerals, which after appropriate heat activation, provide superior N2O decomposition activity. The catalytic process comprises contacting an N2O-containing gaseous mixture with the decomposition catalyst under conditions sufficient to convert the N2O into gaseous nitrogen and gaseous oxygen. The process catalysts are derived from anionic clay materials such as the hydrotalcites, sjogrenites and pyroaurites.
